TO DELINEATE FIRE AREA BY OPTIMIZATIONAL INVERSION OF △T ANOMALY OF POLYGONAL BODY

    Graphical Abstract
    • Abstract
  • By analysing the characters of the △T magnetic anomaly of burnted rock in the fire area, polygonal bodies are. chosed for inversion model. The optimizational inverse method has been employed to delineate borders of the fire area. By damping least squares auto-fit, the iterative several times and ambiguity can are reduced, and accuracy is improved. The theo- retical models and practical data have illustrated the effectiveness of the method.
